LlGHTNlNG-ARRESTER AND CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 591,321, dated October 5, 1897.

- Application filed April 1, 1897. Serial No. 630,276. (No model.)

To all whom, it may concern/i Be it known that I, CHARLEY BRANZELL, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Visconsin, have invented certain new and useful Improvements in Lightning-Arresters and Out-Outs; and ldo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othro ers skilled in the art to which it appertains to make and use the same.

My invention is an improved lightningarrester and cut-out particularly adapted for use in connection with telegraph instru- I 5 ments; and the object of my invention is the provision of a simple and inexpensive instrument of the character named which when an overflow of current or lightning comes over the telegraph-line will act automatically to conduct the overflow current from passing through the telegraph instrument into the ground.

To attain the desired objects the invention consists of a lightning-arrester and cut-out 2 5 embodying novel featuresof construction and combination of parts, substantially as disclosed herein.

Figure 1 represents a top plan view of my arrester and cut-out. Fig. 2 represents a side elevation. Fig. 3 representsafront end view; and Fig. l represents a detail view of ground connection, line connection, and spring. Fig.

' 5 is a bottom plan view, and Fig. 6 is a longitudinal section on line at a; of Fig. 5. 3 5 In the drawings the numeral 1 designates the base, which is attached to a table or suit able support and is provided with the binding-post 2, to which is connected the instrument-terminal, the binding-post 3, to which is connected the ground-terminal, and the binding-post 4:, to which is connected the lineterminal. On the base are mounted the coils 5, which are connected in circuit by the wire 6, and one of the coils is connected by means of the connection 7 with the line binding-post l, and fromv the other coil leads the wire 8, which is connected to the plate 9, from which plate 9 leads the connection 10, which is connected to the instrument binding post 2. From the binding-post 3 leads the connection 11, which forms the ground-circuit, and arranged between the plate 12 and plate 9 is the tip 13, made of insulating material, which is connected by means of a flexible or spring arm 14 to the binding-post 2. At the forward 5 5 end of the spring-arm and adjacent the tip 13 is a lug or plate 13', that normally is in contact with the under side of the plate 9. Arranged above the tip 13 is the copper disk 15, connected to the lever 16, fulcrumed on the rod 17, and provided with the spring adjusting device 18 and carrying the magnet 19, arranged directly over the poles 20 of the magnetic coils.

The operation of my instrument will be readily understood from the foregoing description, taken in connection with the drawings, and I will simply state that in its normal condition the current enters the post 1 from the line-wire, and from thence it is conveyed to the coils by means of the wire 7 and from the coils to the plate 9, and thence through the lug 13 and spring-arm 14 to the post 2, connected with the instrument; but instantly upon an overflow of current or current from lightning comes in over the lines the coils will be highly magnetized, bringing the armature on the lever down upon the poles of the magnet, which action brings the disk on the lever against the tip, forcing the same down, and consequently the spring-arm to which it is attached, thereby withdrawing the lug 13 from contact with the plate 9 and cutting off the current from the instrument and transmitting the same from the plate 9 to the ground-plate 12 through the medium of the disk 10, causing the overflow of current to pass into the ground, and immediately upon the overflow of current being carried off the armature 19 is automatically released 0 from contact with the poles 20 and the springarm allowed to resume its normal position that is, having its lug 13 in contact with the plate 9thereby again forming a connection with the instrument and enabling the latter 5 to operate properly. As will be readily understood, the use of my arrester and cut-out will prevent the telegraph instruments from being burned out and will also allow the telegraph instrument to be used with perfeet safety and accuracy in heavy electrical storms.

I claim- 1. In a lightning-arrester and cut-out, the combination of the base, the coils mounted thereon and connected in circuit, the'plates on the base 1 being connected With one coil and the other being connected with the ground the other coil being connected with the line, a spring connection leading from one of the plates to the instrument-terminal, and the lever fulerunied near its outer end to the base, having an adjustable spring connection leading from its outer end to the base and having its inner end provided With a head or disk for operating on the spring connection and ground and instrument.

In testimony whereof I al'lix my signature in presence of tWo witnesses.
